Y700 Touch 15ISK - Dolby Audio keeps switching to "Voice" preset

‎07-28-201610:43 AM

I have noticed that the Dolby Audio application keeps switching back to the "Voice" preset regardless of what I do or how many times I try to change it. I have opened up the Dolby Audio app itself and changed to a different preset as well as using the Lenovo Settings app to set the "Dynamic" preset as my default, but after some time I find that the settings will always get reverted back to "Voice" again.

In addition to these steps I have also tried updating my audio drivers to the most recent version, but this actually caused the Dolyb Audio app to be completely removed from my machine only to be brought back by first performing a System Restore and then performing a "Repair" operation from the "Uninstall or Change A Program" screen.

I finally located the original Dolby Audio X2 Windows API SDK and Dolby Audio X2 Windows APP installation media (located at "C:\Program Files (x86)\Realtek\Audio\DAX2", not contained in the "LENOVO" hard drive partition which contains all other system drivers) and was able to update my driver and re-install the Dolby software to get it operational again, but the problem of switching profiles persists.

How do I prevent this profile switching, or is it possible to configure the Dolby Audio application to select a profile based on the application that is running? I find having to manually switch my sound profile back to the "Dynamic" preset a pain.

I was still having this problem after trying your fix (ThinkPad e570), every time I focused on Spotify, my Dolby settings would always change back to Music, despite trying mutliple times to set it to a custom EQ.

I found that in the Lenovo Settings application, under "Smart Settings" uncheck "Configure Dolby audio settings to the appropriate mode for different apps you are using". There's nothing smart about that setting... see image for reference.

You can use the Lenovo Vantage app, and go th audio/visual. Then, you should scroll down to dolby settings. You should click one of the options, and then disable application-based settings. hope this helps

I use aHuaweiMatebookm5256 Go (HZ-W19,1stgen tablet), and the audio is also tuned with the Dolby AudioX2Software.

In fact, I hadthe same problemthan other people with a Lenovo device like you. When I turned on the tablet from sleep mode, the Voice mode was automatically enabled.

Firstly, to solve that problem, I simply disabled theDAX2service onstartup. But this solution wasn't great: If there is no difference between a "flat" curve, and no software at all, with a headphone... there's a big difference with speakers!!! The software treatment is really bluffing, even with no specific mode activated ("flat" mode), so it's essential.

So I had to look for a better solution.The fix suggested bypedraodoesn't work for me (not really, I'll explain), and there's no "Smart Settings" function provided byHuawei(or I don't know).

After hours of investigations, digging in theDAX2files and folders, looking (and even spying in real-time) in the Registry, I found something.

In my case, to make it easy,alocal process callaudiodg.execommunicates with theDAX2process, and pushes it to select the Voice profile.

The fix that I'm going to detail doesn't fix the source of the problem at all, but avoidsaudiodg.exe(or whatever program) tointerfere with the Dolby AudioX2software, by denying some permissions.

First of all, it's better to try the fix suggested bypedrao. From my experience, exclusive control features seem impact on permissions.

Open the Registry(by searching regedit.exe in Cortana for exemple)

Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Dolby\DAX(this is the folder containing a key called ActiveProfile, each profile has his own number (Voice = 3))

Right-click on the DAX folder, andopen "Permissions..."

Try to "play" to find the sweet spot(nothing but you can change the profile using the software)

In my case, the group "Everyone" was the owner of the folder, and had the full control of it. Iset System as the owner in "Advanced", and Iremoved "Everyone" in the "Group or user names" listin the "Security" tab.

Do not remove all permissions, or the software won't work at all! Also, you can brake your PC by editing the Registry so be careful!

Now it's seems to work well since two days, so I can enjoy a great sound on speakers, without undergoing this crappy Voice mode all the time.
